Looks interesting and versatile, the Wurkkos DL07 dive light. The main beam looks to have a minimal reflector and be made up of four high CRI Leds. Lists a 135 degree beam angle and 90 CRI. The light also incorporates a single LED with mini reflector spotlight and both red and UV LEDs as can be seen in the photo. All with a magnetic ring for control and powered by a single 26650 battery.

If you do a search on Amazon for “18650 Dive Lights” you can find a number of no name soda can format supposed dive lights with no reflectors and multiple LEDs that appear to be in the Mule format. Below is a link to a page with six of them. I suspect that the claimed lumens outputs are highly questionable and I certainly would not go diving with any of them.

I just watched several reviews on YouTube . I love the b am profile 130 degrees
But I really don’t get the point of red, uv, and two different tint colors
I wish it was just 4 x nichia 519a 4000k instead of Samsung
